"Who's Making Love" is a song written by Stax Records staffers Homer Banks, Bettye Crutcher, Don Davis and Raymond Jackson and recorded by singer Johnnie Taylor in 1968.^[2]

Released on the Stax label in the late summer of 1968, it became Taylor's breakthrough single, reaching number one on the US Billboard R&B chart and number five on the Billboard Hot 100.^[3] It became one of the few singles Taylor would become primarily known for in the mainstream.^{[citation needed]} The song featured the Stax house band, Booker T. & the M.G.'s, and Isaac Hayes (on keyboards).^{[citation needed]} It was Taylor's best-selling single before the release of "Disco Lady" almost a decade later.^{[citation needed]}

According to Bettye Crutcher, the lyrics were inspired by the 1920s novelty song, "Who Takes Care of the Caretaker's Daughter (While the Caretaker's Busy Taking Care)".^[4]
